被検知空間内での被検知物体の接近を検出するための検知部と、スペーサ部材と、被検知空間に磁界を発生させるための第1磁石及び第2磁石とからなる位置検出装置であって、
前記検知部は、前記スペーサ部材を挟んで前記第1磁石と対向する位置に配置されるとともに、前記第1磁石は、前記スペーサ部材と前記第2磁石との間に前記第1磁石が発する磁界の向きと前記第2磁石が発する磁界の向きとが反対となるように配置され、 前記第1磁石の着磁方向および前記第2磁石の着磁方向は、前記検知部、前記スペーサ部材、前記第1磁石および第2磁石が並ぶ方向に対して交差しており、前記第1磁石の着磁方向の長さが、前記第2磁石の着磁方向の長さよりも短くなっており、前記第1磁石と前記第2磁石とが接して配置され、
前記第2磁石からの磁力が前記第1磁石からの磁力よりも被検知空間内において前記検知部からの距離が遠い位置にまで到達して、前記第1磁石からの磁力と前記第2磁石からの磁力との合成により磁界が発生しており、
前記検知部は、被検知空間内を移動する被検知物体により前記第2磁石からの磁力の影響が変化することによる磁界の変化を検出して、被検知物体の接近を検出することを特徴とする位置検出装置。
- 前記第2磁石は、間に磁性部材を挟んで2つの磁石を連結して形成されていることを特徴とする請求項1に記載の位置検出装置。
